I'm getting strange log messages on my Zyxel 3301 Router's System Log regarding devices connected to my TP Link RE650 in WiFi Extend Mode - see screenshot below for a typical log entry - 192.168.1.246 is a Sky Q box. These messages only relate to to devices connected to it, other devices on the same WiFi network do not cause these messages and if I move an extended device to straight WiFi they do not cause such messages.

Sometimes the messge relates to the ip address of the 650 itself.

Looking at the log on the 650 itself there are no events recorded on or about the time of these messages.

Can anyone help with this please.

Thanks In Advance.
